LAFAYETTE, Ind. — A mother and her adult son lay dead — or near death — in the 800 block of Eastwich Drive Thursday night after a 9:30 p.m. shooting in this otherwise quiet, working-class neighborhood just north of Union Street.

"My wife ...," said neighbor Sergio Requenes, "she heard the shots, and when she came outside of the house, they were both laying in the street. Then she called me at work.

"I knew the gentleman," he said. "I talked with him occasionally. He was a pretty good dad. He’d take his kids out to walk, to games."

Tippecanoe County Coroner Donna Avolt released the victims' names about 2:30 p.m. Friday.

The woman who was killed is 67-year-old Catalina Lujano-Campuzano. Her son was Gustavo Sanchez-Campuzan, 38.

Both were shot four times at intermediate range, Avolt said, citing the findings of Friday's autopsy.

Sanchez-Campuzan was struck in the neck, the trunk and abdomen. Lujano-Campuzano was struck in the shoulder, upper chest and middle chest, Avolt said.

Police said they suspected 52-year-old Franco Navarrete was the triggerman.

Police caught up with Navarrete Friday morning, Lafayette police Sgt. Matt Gard said at 11:30 a.m. Detectives questioned him throughout the morning and into the afternoon.

They formally arrested Navarrete about 3 p.m. Friday, preliminarily charging him with two counts of murder.

Sanchez-Campuzan and Lujano-Campuzano were shot three houses south of their Eastwich Drive home.

Mike Mitchell saw the shooting from his picture window.

“I saw the car pull up, the person get out of the car, the person got back into the car," he said. "I couldn’t tell how many people were in the car. I saw flashes as the car drove off.”

Those flashes were gunshots — five or six of them, as Mitchell described. Another neighbor who didn't want to be identified was outside at the time of the shooting and heard three gunshots, a pause, then three more shots.

At the victims' home Friday morning, a steady stream of friends and family parked in the yard and along the street. There were hugs of condolences as well-wishers greeted the grieving family in the front yard or at the front door, followed by a retreat inside the house out of sight to neighbors who respectfully watched from a distance.

The violence of the attack in this otherwise quiet neighborhood stunned the neighbors.

"I'm in shock because of how violent it was,” Requenes said, adding that Sanchez-Campuzan leaves behind three kids ranging between 10 and 14 years old.

"It's horrible. To see this happen to our neighbor,” he said. "Nothing like this ever happened here."Reach Journal & Courier reporter Ron Wilkins at 765-420-5231.
